The short answer is simple:
- Choose AVIF if you want the smallest file sizes and the best image quality for modern websites.

In this complete guide, we’ll compare AVIF and JPG side by side, explain their strengths and weaknesses, and help you choose the right format for your needs.
Do you want to convert AVIF to JPG online?
What is AVIF?
AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec. It was designed to provide exceptional compression while maintaining impressive visual quality.
Compared to older formats, AVIF can significantly reduce image file sizes without creating noticeable quality loss. It also supports modern features like transparency, HDR images, wide color gamuts, and higher bit depth.
What is JPG?
JPG (or JPEG) is one of the world’s most popular image formats. Introduced in the early 1990s, it remains the standard format for digital cameras, websites, smartphones, social media, and document sharing.
Almost every operating system, browser, image editor, printer, and website supports JPG without additional software.
Its biggest strength is universal compatibility.

AVIF vs JPG File Size
One of the biggest reasons people switch to AVIF is file size.
Independent tests consistently show AVIF images can be 30% to 70% smaller than JPG images while maintaining similar visual quality. The exact savings depend on the image content and encoder settings.
Smaller files mean:
- Faster website loading
- Lower bandwidth usage
- Reduced storage costs
- Better Core Web Vitals
- Improved SEO performance
If page speed matters, AVIF has a clear advantage.
AVIF vs JPG Image Quality
AVIF uses much newer compression technology than JPG.
At the same file size, AVIF generally preserves:
- Fine textures
- Sharp edges
- Smooth gradients
- Color accuracy
- Image detail
JPG tends to produce visible compression artifacts at lower quality settings, such as:
- Blockiness
- Color banding
- Blurred edges
- Noise around text
This makes AVIF especially attractive for high-quality web photography and large hero images.
Browser Compatibility
Compatibility is where JPG still shines.
JPG
Works virtually everywhere:
- Chrome
- Firefox
- Safari
- Edge
- Windows
- macOS
- Linux
- Android
- iPhone
- Smart TVs
- Cameras
- Image editors
AVIF
Modern browser support is now widespread, including current versions of Chrome, Firefox, Edge, and Safari, but some older software and legacy operating systems may still lack native support.
If you’re sharing images with unknown users, JPG remains the safest choice.
Website Performance
Search engines reward fast websites.
Because AVIF images are much smaller, websites often experience:
- Faster loading pages
- Better mobile performance
- Lower bounce rates
- Reduced server bandwidth
- Improved user experience
Research has shown newer formats such as AVIF can improve page load performance compared with JPEG when used appropriately.
If you’re optimizing a website for SEO, AVIF is an excellent option.
Editing Support
JPG has decades of software support.
Nearly every program can open, edit, and save JPG images.
AVIF support continues to improve across modern editing software, but older applications may still require plugins or updates before they can edit AVIF files properly.
Encoding Speed
Another important difference is speed.
JPG
- Encodes very quickly
- Ideal for batch processing
- Lower CPU usage
AVIF
- Produces better compression
- Takes longer to encode
- Requires more processing power
If you’re converting thousands of images every day, encoding time may influence your workflow.
